I am learning as "you" go here! Mine is like Jim's van. DG could also be Dark Green. There should be a legend somewhere in your manual.
The other day I was looking at a schematic in my manual and it listed a initial that was not in the legend... so

When you took the module apart, did you pull the circuit board out of the plastic housing and look real close on the back side for bad solder connections? Sometimes a magnifying glass and good light help with that.

You are saying there is no power going to the module from fuse 9?

also: To me I see the discrepancy you are talking about between the two pages and ohms. I don't have the answer for that. perhaps someone else will be able to answer..

Try not to get frustrated as it makes it harder.. Maybe instead of thinking about fixing it so much, think more in the line that you are learning how that system functions.. Once you have it fixed, you'll be able to help others as well a make repairs if you have a problem again.

In the mean time, if you need to drive, clean the windshield real good and apply some Rain-X. That is what I did with my 95 GMC that the wipers only worked when they wanted to. It works best applying it on a dry day but I learned that in an emergency it can be applied on a rainy day under cover..

 

Yes, it is a useful learning experience. As a side note, when I pulled the ignition keylock out, there is a small plastic tab on the contactor for the key-in-ignition chime that broke off. Very thin plastic just fatigued at end of life. But, without it the key chime doesn't shut off. So, I just left it out. Got rid of the annoying chime!

Anyway, It wasn't the wiper module I disassembled it was the MF switch. I will probably pull and disassemble the module and look at the board once we get the questions resolved with the MF switch.

Hope someone can comment on the values listed above...

 

well the module looks fairly simple inside..

IF you were an electronics guru you could probably find the parts if any were bad..
here is at least one..

My EVTM for your year and chassis doesn't approach the component testing the same way as the service manual. Unfortunately I can't reproduce or post an image here because my EVTM's are all printed form. I'll try to take a photo and post that but don't delay your progress waiting for that. Should I be able to do so I'll post here and PM you too.

You're also welcome to post this same question in FTE's Electrical & Wiring sub-forum. This isn't an uncommon problem, the F-Series very similar to the E-Series so plenty of experience to be found there.

Sorry I can't pinpoint your exact failed component.

 

Great idea, JWA. So that description between the two posted above seems confusing to you also?

The manual pics here I just snapped with the Ipad. Handy little tool.

 

Correct---the discrepancies you've found could be misleading. Sadly my camera cannot adequately capture an image suitable to share with you--its unreadable.

At this point I'm lost how to help---definitely post this same situation in the Electrical sub-forum for more specific and directed help.

 

Solved!

The workshop manual and wiring diagrams are essential to understanding. Using the diag tests early on lead to the wiper control module. The hot pins to the washer and wiper circuits had no power. Circuit 65 in diagram. It appeared to be a loose terminal, one of the DG wires not making adequate contact seemed to be the probem because after shoving the wire tighter into the connector another check with volt meter revealed 12v. I did pull the Wiper Control Module out and look at the board to verify no broken joins. (that saved $231!). Reassembed it and plugged in the connector. Wipers and washer working. Before stuffing all back under the dash, I pulled twisted and turned the harness and could not cause the malfunction again. So, it's done. For now, but kind of dissapointing I didn't have to do more detective work and find an outright physical break or short. It was more like the gremlins just got tired of screwing with me.

So now, to tackle the non-working Cruise Control which I've just been ignoring for a long time. Maybe I'll start a new thread.

 

Great! Indeed the Ford manuals are important and helpful so many times--I always advocate any DIY mechanic to at least have the correct year EVTM for their van.

Definitely start a new thread for the cruise control or as Ford calls it Vehicle Speed Control. List your year and whether the current VSC is factory installed or aftermarket.

 

Love it when a plan comes together! :-)

When the headlights on the wife's Explorer quit, I googled the problem and learned the dealers were replacing lighting modules for 600 bucks, I knew I was going to teach myself about lighting modules. Mine (once I found it) was a bad solder connection. One minute with an iron, and fixed.

Great followup post, looking forward to seeing the speed control episode next. jim
